Module partitioned_execution 

Rank-local graph execution over opaque communication resources. Backend-neutral rank-local execution over opaque communication resources.

Architecture adapters remain statically dispatched and own tensor equations, routed providers, and typed boundary encoding. This module owns the common partition schedule, mechanical wire validation, exact completion, publication, and the execution strategy installed in crate::ReplicatedTextSession.

Structs

LayerwiseTraversalPartitionExecutor

Reusable executor for one architecture-owned, fully local traversal inside a neutral partitioned runtime.

NoBoundaryTransport

Proof that this execution path selects no point-to-point boundary routes.

NoCommitAgreement

Proof that this execution path selects no distributed commit barrier.

NoOutputPublisher

Proof that this execution path selects no root-to-group publication.

OpaqueBoundaryTransport

Point-to-point boundary transport requiring no collective capabilities.

OpaqueCommitAgreement

Barrier commit agreement requiring no tensor communication capabilities.

OpaqueFailureAgreement

Explicit all-rank failure propagation and final commit agreement.

OpaqueOutputPublisher

Broadcast output publication requiring no point-to-point or barrier capability.

PartitionBoundaryRoute

One exact directed architecture boundary after a graph group completes.

PartitionCommunication

Opaque native communication resources paired in manifest order.

PartitionCommunicationAuthority

Cloneable bounded-completion and poison authority for one selected communication session.

PartitionOutputAuthority

Exact public-output authority projected into one selected communication group.

PartitionOutputPublication

Authoritative output owner and opaque publication group.

PartitionedExecutionPlan

Immutable rank-local execution and communication plan.

PartitionedTextExecution

Stateless strategy marker selecting PartitionedTextRuntime in the shared session.

PartitionedTextRuntime

Complete rank-local runtime installed behind the shared replicated session.

RealizedCommunicationGroup

One backend-native group paired with the opaque identity selected by the manifest.

RealizedCommunicationRoute

One backend-native route paired with the opaque identity selected by the manifest.

Enums

DistributedExecutionPhase

Canonical shared-session phases whose local status must be propagated.

LayerwiseTraversalRuntime

Neutral choice between an ordinary local traversal and the same traversal installed in a selected partition runtime.

PartitionExecutionError

Cold-path validation or execution failure in the neutral partition driver.

PartitionedTraversalError

Failure while a fully local layered traversal runs through a selected partitioned runtime.

Traits

CommunicationTensorMetadata

Backend-native tensor metadata used only for mechanical communication validation.

PartitionBoundaryTransport

Additive policy for an optional point-to-point boundary path.

PartitionCommitAgreement

Additive policy for optional distributed state-commit agreement.

PartitionOutputPublisher

Additive policy for optional root-owned output publication.

PartitionedGroupExecutor

Statically dispatched architecture/provider adapter used by the production driver.

Type Aliases

PartitionedTraversalResult

Output of one architecture-owned traversal through a neutral partition runtime.
